Specification forming part ofLetters Patent No. 16,673, dated March 7,1865.

To all whom iz? may concern:

Be it known that I, WALTER HYDE, of No. 769 Broadway, (room 21,) in thecity, county, and State of New York, have invented a new and ImprovedWell-Borer 5 and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the saine, reference being had to theaccompanying drawings, forming a part of this specication, in which-Figure l represents a horizontal section of this invention, the linema', Fig. 2, indicating the plane of section. Fig. 2 is a side elevationof the same. Fig. 3 is a detached elevation of a device for removingbroken drills. Fig. 4 is a detached sectional elevation of a borer usedin clay or soft ground. Fig. 5 is an end view of the same.

Similar letters of reference indicate like parts.

This invention consists in the arrangement of an oscillating lever whichhas its fulcrum ou a pivot secured in an uprightpost, and

' which is provided with a roller at about the middle ot' its length tooperate in combination with the rope from which the borer is suspended,and with a windlass and tappetwheel, in such a manner that when therope, after having been wound round the windlass, is drawn through underthe roller in the oscillating lever and over a pulley in the top of theupright post, any up-and-down motion imparted to the roller in theoscillating lever produces twice as much motion of the drill-that is tosay, if the roller be depressed one inch the drill rises two inches, andvice versa, and by these means the height of the stroke is doubled. Avdouble gear is attached to the windlass and a hand-crank to the pinion.By means of this crank the drill is easily raised or lowered, accordingto the pleasure of the operator, whether the machine is in motion ornot, and the danger of breaking the drill is avoided, which ariseseither from too large an accumulation of drillin gs in the well orfromthe fact of the drill getting into bad openings in the rock.Furthermore, the height of the stroke can be adjusted to a fraction ofan inch. For the purpose of holding the drill when the joints areloosened a pair of shears are ap.- plied to the platform, which arelocked to gether by a catch, so that they hold securely i all the weightbelow against any accident. Two windlasses are combined with theboring-` machine-one to contain the drill-rope and intended to be workedby a belt from the main or y-wheel shaft of the machine, and the otherto contain the bracket-rope and intended to be operated by han d--saiddouble windlass beingl applied in combination with a stirrup catchingover pins projecting from the sides of the upright post in such a mannerthat the drill can be readily raised and the drill-hole bored out at anymoment.

A representsa platform or frame of wood or any other suitable material,and supported by'wheels, if desired, so that it can be readilytransported from place to place. From this platform rises a post, B, toa height of twenty feet, (more or le'ss,) and through the lower part ofthis post passes a pin, a, which formsl the fulcrum for a lever, C.

D is a windlass, which has its bearings in lugs or brackets b, securedto the sides of the post B and a rope, E', which is wound on saidwindlass, one ot' its ends being secured to the same, extends under apulley, c, which is situated in a mortise in the lever G, and has itsbea-ring on a pin, d, passing transversely through said lever, asclearly shown in Fig. 1 of the drawings, and thence the rope passes upover a pulley, e, secured on the top end of the post B, and it connectswith a swivel, j', fastened in the upper end of the drill-rod.

Mounted on the shaft of the windlass D is ay cog-wheel, g, which gearsin a pinion, h, and a handle, i, which is secured to the end of thearbor of said pinion, serves to turn the windlass in either direction,so as to raise or lower the drill, 'as may be desired. A pawl, j, whichVengages with the teeth of the cogwheel g, prevents the same from turningbackward and holds the drills at the desired height. The

lever C extends through a slot in the standard E, which rises from theplatformA A, and

its point is exposed to the actionof cams or tappets, k, which aremounted on the main shaft F of the machine. These cams are so shapedthat they depress gradually the tip of the lever, and in order to reducethe friction said tip may be protected by a metal plate, or afriction-roller may be inserted in it. The main shaft F is revolved bythe action of a belt stretched over the iiy-wheel G, and driven by asteam-engine or other suitable source Vof power, and if it is desired tointerrupt or stop the action of the cams on the lever C said lever isdepressed, and a pin, l, is passed through the standard E, as shown inFig. 2 of the drawings.

If the lever C is depressed, the distance between the pulley c andthewindlass and also between said roller and the pulley e is increased, andconsequently both branches of the drill-rope--viz., that between thewindlass and pulley c and that between .the pulley'c and e-arelengthened, or, in other words, a quantity of rope is taken up equal tothe double motion of the pulley c, and consequently the height to whichthe drill is raised is twice as large as the downward motion of thepulley c. By this arrangement the stroke of the drill can be increasedto any desired eX- tent. The drill-rod H is connected to the swivel f sothat the same can easily revolve in either direction, and if the lever Cis depressed so that the drillrope is strained and the drillrodsuspended above the bottom of the hole already drilled, the ropeuntwists slightly, and the drill, together with the drillrod,revolve inone direction, but as soon as the drill strikes and the strain is takenoli' from the rope the latter resumes its original twist and the swivelturns independent of the drill rod. An intermittent rotary motion isthus irnparted to the drill without the aid of a complicated mechanism,and the operation of drilling is thereby considerably facilitated. 'Ihedrill-rod is composed of a series of section s, which are united bycouplings m. These couplings are made square at their lower ends, and ifit is desired to insert a new sect on, the square part of the last oruppermost After the drill-rod has been adjusted to the desired lengththe drill is let down; by turning the windlass back, and when the pointof the drill touches, the bottom of the hole the pawl j is thrown ingear with the cogwheel g, and by turning the pinion in the properdirection the stroke of the drill can be readily adjusted. If thedrill-rope is taut when the point of the drill touches the bottom of thehole the full stroke of the lever G is transmitted to the drill, but ifthe dri1l rope is slack when the point of the drill touches the bottomof the hole a portion of the stroke of the lever is taken up by theslack of the rope, or if the windlass is 4turn'ed so that the point ofthe drill is slightly elevated above the bottom of the hole theblowexertedV by the drill will be light, and it can b e adjusted atpleasure.

The drill D* is secured'in the lower end of "in Fig. 3i of the drawings.

the drill-rod, and its pot is made about twenty inches vin length andfour inches wide, of the best cast-steel, and provided with lips orflanges two inches wide by twenty inches in length and three-eighths ofan inch inthickness.

For the purpose of removing broken tools I use. a drill-extractor T,such as represented It is provided with a cork-screw, s, similar to thecoil used on "rmrods lof lire-arms, which is intended to `work itselfover the end of that portion of therod or tool remaining in the hole,and a .loose ring, r, catches over said end, and when the extractor 'isdrawn up it retains the rodor tool caught in` this ring and raises it upto the surface.

For boring into clay or soft ground I use a tool, D2, such asrepresented in Figs. 4 and5.

drill the air is allowed to pass down and they operation of raising thedrill is facilitated.

For the purpose of raising the drill-rod, and

also to raise and lower the bucket which. serves to clear out the dirtand rubbish` accumulating in the hole, I use a double windlass, W W', tooneof which motion is imparted by a belt, K, from the main shaft,whereas the other windlass, W', is turned by a handcrank, L.

The rope Efrcm the windlassWisfurnished with a sheave, n', suspendedfrom a hook, o, which catches in a stirrup, S, which is adjustf able onpins o', projecting from the edges of the post B. A similar sheave andhook are attached to the rope E", which winds on the windlass W', andfrom which the bucket B" is suspended. By this arrangement both thedrill-rope and the bucket-rope are in such a position that they can beconveniently operated, and the drill as well as the bucket can belowered to or raised from a depth of six hundred or more feet withlittle troubleor loss of time.

The several sections of the drill-rod, when the same are not used, arelaid inv a trough, P,which is necessary not only to keep them from theground, but to steady and guide their lower ends when the same areraised one by one andlowered in the well. This arrangement enables oneman to manage the rods, i

by the rope, and has perhaps cut away the f rock half an inch, and heleisurely slackens the rope by the hand-gear and crank on the post, andthe operation goes on without interruption.

3. The shears I, applied in combination with the platform A andsectional drill-rod H, substantially as and for the purpose specified.

4. The use of a double Wind1ass,WW/, and adjustable stirrup S, incombination with the drillrope E and bucket-rope E, constructed andoperated substantially as and for the purpose described.
